SARS-CoV-2 detection dogs - a pilot study
<p>The outstanding olfactory acuity of canines led us to consider whether dogs are able to reliably detect the odour of respiratory diseases associated with a SARS-CoV-2 infection in saliva or tracheobronchial secretion of hospitalized COVID-19 patients. Furthermore, we examined if SARS-CoV-2 detection dogs could provide an appropriate screening method for the human virus.The aim of this data publication is to provide the data acquired in the controlled, randomized and double-blinded pilot study `Scent dog identification of SARS-CoV-2 infection’ (submitted to BMC Infectious Diseases).</p>
Data from: Ecology of domestic dogs (Canis familiaris) as a host for Guinea worm (Dracunculus medinensis) infection in Ethiopia
<p>The global programme for the eradication of Guinea worm disease, caused by the parasitic nematode <i>Dracunculus medinensis</i>, has been successful in driving down human cases, but infections in non-human animals, particularly domestic dogs (<i>Canis familiaris</i>), now present a major obstacle to further progress. Dog infections have mainly been found in Chad and, to a lesser extent in Mali and Ethiopia. While humans classically acquire infection by drinking water containing infected copepods, it has been hypothesised that dogs might additionally or alternatively acquire infection via a novel pathway, such as consumption of fish or frogs as possible transport or paratenic hosts. We characterised the ecology of free-ranging dogs living in three villages in Gog woreda, Gambella region, Ethiopia in April–May 2018. We analysed their exposure to potential sources of Guinea worm infection, and investigated risk factors associated with infection histories. The home ranges of 125 dogs and their activity around water sources were described using GPS tracking, and the diets of 119 dogs were described using stable isotope analysis. Unlike in Chad, where Guinea worm infection is most frequent, we found no ecological or behavioural correlates of infection history in dogs in Ethiopia. Unlike in Chad, there was no effect of variation among dogs in their consumption of aquatic vertebrates (fish or frogs) on their infection history, and we found no evidence to support hypotheses for this novel transmission pathway in Ethiopia. Dog owners had apparently increased the frequency of clean water provision to dogs in response to previous infections. Variations in dog ranging behaviour, owner behaviour and the characteristics of natural water bodies all influenced the exposure of dogs to potential sources of infection. This initial study suggests that the classical transmission pathway should be a focus of attention for Guinea worm control in non-human animals in Ethiopia.</p>
Data from: Whole-genome analyses provide no evidence for dog introgression in Fennoscandian wolf populations
<p>Hybridisation and admixture can threaten the genetic integrity of populations and be of particular concern to endangered species. Hybridisation between grey wolves and dogs has been documented in many wolf populations worldwide and is a prominent example of human-mediated hybridisation between a domesticated species and its wild relative. We analysed whole-genome sequences from >200 wolves and >100 dogs to study admixture in Fennoscandian wolf populations. A principal component analysis of genetic variation as well as Admixture showed that wolves and dogs were well separated, without evidence for introgression. Analyses of local ancestry revealed that wolves had <1% mixed ancestry, levels comparable to the degree of mixed ancestry in many dogs, and likely not resulting from recent wolf-dog hybridisation. We also show that the founders of the Scandinavian wolf population were genetically inseparable from Finnish and Russian Karelian wolves, pointing at the geographical origin of contemporary Scandinavian wolves. Moreover, we found Scandinavian-born animals among wolves sampled in Finland, demonstrating bi-directional gene flow between the Scandinavian peninsula and eastern countries. The low incidence of admixture between wolves and dogs in Fennoscandia may be explained by that feral dogs are rare in this part of Europe, and that careful monitoring and management act to remove hybrids before they backcross into wolf populations.</p>

Spatial and temporal dynamics of space use by free-ranging domestic dogs Canis familiaris in rural Africa
<p>Variation in the spatial ecology of animals influences the transmission of infections and so understanding host behaviour can improve the control of diseases. Despite the global distribution of free-ranging domestic dogs <i>Canis familiaris</i> and their role as reservoirs for zoonotic diseases, little is known about the dynamics of their space use. We deployed GPS loggers on free-ranging dogs from six villages in rural Chad, and tracked the movements of 174 individuals in the dry season and 151 in the wet season. We calculated 95% and core home ranges using auto-correlated kernel density estimates (AKDE<sub>95</sub> and AKDE<sub>core</sub>), determined the degree to which their movements were predictable, and identified correlates of movement patterns. The median AKDE<sub>95 </sub>range in the dry season was 0.54km<sup>2</sup> and in the wet season was 0.31km<sup>2</sup>, while the median AKDE<sub>core </sub>range in the dry season was 0.08km<sup>2</sup> and in the wet season was 0.04km<sup>2</sup>. Seasonal variation was, in part, related to owner activities. Dogs from hunting households had ranges that were five times larger in the dry season. At least 70% of individuals were more predictably 'at home' (<50m from the household) throughout the day in the dry season. 80% of dogs demonstrated periodicity in activity levels (speed) and just over half the dogs exhibited periodicity in location (repeated space use). In the wet season, dogs mostly exhibited 24-hour cycles in activity and location, with peaks at midday. In the dry season, dogs exhibited both 12 and 24-hour cycles, with either a single peak at midday, or one peak between 6am and 12 noon and a second between 6 and 10pm. Strategies to control canine-mediated zoonoses can be improved by tailoring operations to the local spatial ecology of free-ranging dogs. Interventions using a door-to-door strategy in rural Chad would best conduct operations during the dry season, when access to dogs around their household more reliably exceeds 70% throughout the day. Given the importance of use in hunting for explaining variation in dog space-use, targeting approaches to disease control at the household level on the basis of owner activities offers potential to improve access to dogs.</p>
Ecology of domestic dogs Canis familiaris as an emerging reservoir of Guinea worm Dracunculus medinensis infection
<p>Global eradication of human Guinea worm<i> </i>disease (dracunculiasis) has been set back by the emergence of infections in animals, particularly domestic dogs <i>Canis familiaris</i>. The ecology and epidemiology of this reservoir is unknown. We tracked dogs using GPS, inferred diets using stable isotope analysis and analysed correlates of infection in Chad, where numbers of Guinea worm infections are greatest. Dogs had small ranges that varied markedly among villages. Diets consisted largely of human staples and human faeces. A minority of ponds, mostly <200 m from dog-owning households, accounted for most dog exposure to potentially unsafe water. The risk of a dog having had Guinea worm was reduced in dogs living in households providing water for animals but increased with increasing fish consumption by dogs. Provision of safe water might reduce dog exposure to unsafe water, while prioritisation of proactive temephos (Abate®) application to the small number of ponds to which dogs have most access is recommended. Fish might have an additional role as transport hosts for Guinea worm, by concentrating copepods infected with worm larvae.</p>
African wild dog dispersal and implications for management
Successful conservation of species that roam and disperse over large areas requires detailed understanding of their movement patterns and connectivity between subpopulations. But empirical information on movement, space use, and connectivity is lacking for many species, and data acquisition is often hindered when study animals cross international borders. The African wild dog (Lycaon pictus) exemplifies such species that require vast undisturbed areas to support viable, self‐sustaining populations. To study wild dog dispersal and investigate potential barriers to movements and causes of mortality during dispersal, between 2016 and 2019 we followed the fate of 16 dispersing coalitions (i.e., same‐sex group of ≥1 dispersing African wild dogs) in northern Botswana through global positioning system (GPS)‐satellite telemetry. Dispersing wild dogs covered ≤54 km in 24 hours and traveled 150 km to Namibia and 360km to Zimbabwe within 10 days. Wild dogs were little hindered in their movements by natural landscape features, whereas medium to densely human‐populated landscapes represented obstacles to dispersal. Human‐caused mortality was responsible for >90% of the recorded deaths. Our results suggest that a holistic approach to the management and conservation of highly mobile species is necessary to develop effective research and evidence‐based conservation programs across transfrontier protected areas, including the need for coordinated research efforts through collaboration between national and international conservation authorities.
Dog Carving - Abby
This artifact is a wood carving of a dog. It is extremely fragile, and is made of a type of wood. The artifact is about 3 inches by two inches and is missing all but one leg. It was most likely from the Victorian era, or 1829 to 1860. The artifact was probably used as either a toy, or an art piece. The act of carving this piece also could have been a pastime for a person. This artifact could fall into the category of art and cultural expression, because it could have been an art piece, childhood vs. adulthood because it may have been a toy, and it could be in technology/technological change because it was definitely hand carved, and was not made by a machine that we would have today.

Roman Dog Skull
This dog skull from the Roman period was found in what we think was a well at the County Sports site in Staines in the early 1980s. Nick, our curator, was working at the site under the direction of Rob Poulton, cleaning a circular feature. The circular feature started to subside and Nick had to be rescued from falling in! Timbers suggestive of a well lining were found and 15 individual dogs were identified, all male, of which this is one. This and four other dog skulls are on display in the museum. Other items found in the well were a Nene valley ware 'hunting cup' showing dogs and stags, a large greyware jar, and a red deer antler. Source: Objaverse 1.0 / Sketchfab

Livestock guardian dogs establish a landscape of fear for wild predators: implications for the role of guardian dogs in reducing human-wildlife conflict and supporting biodiversity conservation
<ol> <li>Livestock guardian dogs (LGDs) are increasingly used to protect livestock from predators, but their effects on the distribution and behaviour of wild predators are mostly unknown. A key question is whether LGDs exclude predators from grazing land, or if predators continue to use areas with LGDs but modify their behaviour in ways that reduce impacts on livestock.</li> <li>We studied effects of LGDs (Maremma sheepdogs) on distribution and behaviour of red foxes Vulpes vulpes in north-eastern Victoria, Australia. We mapped the activity of LGDs across the study areas using GPS tracking and measured fox activity using remote cameras. We also measured risk-sensitive foraging in foxes to test if they reduced feeding time at sites regularly used by LGDs.</li> <li>Foxes occurred throughout areas occupied by LGDs, but their probability of detection was negatively related to probability of LGD presence. Foxes extracted fewer food items from experimental food stations in proportion to the intensity of local activity of LGDs. This indicates that though foxes overlapped with LGDs, they responded to risk of encountering LGDs by allocating less time to foraging. </li> <li>While LGDs do not necessarily exclude wild predators from areas used for livestock production, they can have strong effects on predator behaviour. Reduction in time allocated to foraging in areas regularly used by LGDs could lead to suppression of hunting behaviour and therefore a reduction in attacks on livestock. The flexible response of predators to LGDs should facilitate coexistence of wild predators with livestock farming, by allowing predators to continue to use areas occupied by livestock while still preventing attacks on those livestock. Our results therefore strengthen the case for use of LGDs in the conservation of predators threatened by conflict with farming. Suppression of hunting behaviour should also mean that prey species experience reduced rates of predation on farmland with LGDs. This effect could be valuable for conservation of threatened species of prey.</li> </ol>
